Listview Question

3 posts in this topic

Is there a good way while a script is running, to do the following...

When any item in a listview/treeview is clicked, write the value of the item clicked to a main script variable that would change each time an item is clicked.

How would I go about doing that?

if the ListView is created useing autoit here's one way:

#include <GuiConstants.au3>
#include <GuiListView.au3>

Global $ListView
Global Const $WM_NOTIFY = 0x004E
Global Const $DebugIt = 1

$main_GUI = GUICreate("GuiRegisterMsg Test", 225, 400, 300, 10, BitOR($WS_THICKFRAME, $WS_SIZEBOX))

$ListView = GUICtrlCreateListView("Entry Name|Category", 5, 5, 195, 280, BitOR($LVS_SORTASCENDING, $LVS_SINGLESEL))
_GUICtrlListViewSetColumnWidth($ListView, 0, 100)
_GUICtrlListViewSetColumnWidth($ListView, 1, 100)
GUICtrlCreateListViewItem("Name 1|Category 1", $ListView)
GUICtrlCreateListViewItem("Name 2|Category 2", $ListView)
$lbl = GUICtrlCreateLabel("", 5, 295, 195, 20, $SS_SUNKEN)

;Register WM_NOTIFY  events
GUIRegisterMsg($WM_NOTIFY, "WM_Notify_Events")

While 1

    $msg = GUIGetMsg()

    Switch $msg

        ;This case statement exits and updates code if needed
        Case $GUI_EVENT_CLOSE

            ;put all the misc. stuff here
        Case Else

Func ListView_Click()
    If $DebugIt Then _DebugPrint("$NM_CLICK")
    GUICtrlSetData($lbl, _GUICtrlListViewGetItemText($ListView, _GUICtrlListViewGetSelectedIndices($ListView)))
EndFunc   ;==>ListView_Click

Func ListView_DoubleClick()
    If $DebugIt Then _DebugPrint("$NM_DBLCLK")
    MsgBox(0, "Double Clicked", _GUICtrlListViewGetItemText($ListView, _GUICtrlListViewGetSelectedIndices($ListView)))
EndFunc   ;==>ListView_DoubleClick

; WM_NOTIFY event handler
Func WM_Notify_Events($hWndGUI, $MsgID, $wParam, $lParam)
    #forceref $hWndGUI, $MsgID, $wParam
    ;ListView Events
    Local Const $NM_FIRST = 0
    Local Const $NM_CLICK = ($NM_FIRST - 2)
    Local Const $NM_DBLCLK = ($NM_FIRST - 3)
    Local $tagNMHDR, $event, $hwndFrom, $code
    $tagNMHDR = DllStructCreate("int;int;int", $lParam) ;NMHDR (hwndFrom, idFrom, code)
    If @error Then Return
    $event = DllStructGetData($tagNMHDR, 3)
        Case $wParam = $ListView
                Case $event = $NM_CLICK
                Case $event = $NM_DBLCLK
    $tagNMHDR = 0
    $event = 0
    $lParam = 0
EndFunc   ;==>WM_Notify_Events

Func _DebugPrint($s_text)
    $s_text = StringReplace($s_text, @LF, @LF & "-->")
    ConsoleWrite("!===========================================================" & @LF & _
            "+===========================================================" & @LF & _
            "-->" & $s_text & @LF & _
            "+===========================================================" & @LF)
EndFunc   ;==>_DebugPrint

Don't argue with an idiot; people watching may not be able to tell the difference.

I have a quick question, is there definitions about windows message ID (WM_MSG) ?

MsgBox(0, "Steven Seagal", "Les poches bourrées de Pesos")
